FIELD: mechanical engineering. SUBSTANCE: fastening pieces production line has feeding, main heating, deformation and forging and pressing apparatuses. Main heating apparatus is located between deformation and pressing and forging apparatuses and is made in the form of through furnace of flame heating. Between feeding apparatus and deformation apparatus there is additional heating apparatus linked by gas passage with main heating apparatus. Feeding apparatus is made in the form of rack and driving rollers. Space between deformation and pressing and forging apparatuses is equal to 1.1 - 1.5 of rack length. In front of main heating apparatus and after it additional feeding mechanisms ar located. EFFECT: improved design. 1 dwg
